Former NYPD detective Bo Dietl told Sean Hannity Al Sharpton's contention that he did not know he was an FBI informant in the 1980s is "a lot of baloney."
Sharpton fiercely maintained in a press conference earlier today that he was not a "rat" following revelations Sharpton attempted to buy cocaine from an undercover FBI agent.
Dietl, speaking Tuesday evening on Fox News, revealed the NYPD had a special nickname for Sharpton after the current MSNBC host became an informant:
BO DIETL: There was a lot of involvement with the music industry at that time that Al was involved in. And then all of the sudden we used to pass through East Harlem, and everyone knew it. We used to call him the fat rat.
SEAN HANNITY: What do you make of that video with cocaine?
DIETL: The video stands for itself right there. He was talking about buying kilos of coke with an undercover. So who is he representing?
HANNITY: Do you think that resulted in him becoming -- he was flipped as a result of that because they threatened to indict him?
DIETL: The majority of the times when we develop informants is when you get them on a felony case and then you flip them and they become an informant. When he says he didn't know he was an informant that's a lot of baloney. al sharpton knew what he was doing, he was cooperating with the FBI.
